SSF净化(suspended sludge filtration)是一种新兴的污水处理技术,其在处理量为1.8×104m3/d大型污水处理站的首次应用中,取得了较好的效果,可达到ρ(油)≤10 mg/L、ρ(SS)≤15 mg/L的指标,克服了常规流程二次沉降罐沉降分离效果差、处理效率低等问题。SSF净化装置投加混凝剂65.00 mg/L、助凝剂0.84 mg/L,药剂成本约0.31元/m3。该工艺流程短、运行成本低、投资省,适用于来水水量水质相对稳定的污水处理站。
As an emerging wastewater treatment technology, suspended sludge filtration (SSF) has achieved good results in the first application of a large-scale wastewater treatment plant with a capacity of 1.8 × 10 4 m 3 / d and can achieve ρ (oil) ≤10 mg / L and ρ (SS) ≤15 mg / L, which overcomes the problems of poor sedimentation efficiency and low treatment efficiency in the secondary sedimentation tank in the conventional process. SSF purification device dosing coagulant 65.00 mg / L, coagulant 0.84 mg / L, pharmaceutical costs about 0.31 yuan / m3. The process is short, low operating costs, investment in the province, for water quality is relatively stable water treatment station.
